complément m (plural compléments)[1]
Etymology
It is borrowed from Latin complēmentum (“that which completes”), formed from compleō (“to fill up, finish, perfect”).[2][3][4] The Grand Robert and the Petit Robert date the word to 1308 but say that it was taken up again in 1690.[5][6] Bloch and Wartburg date it only from 1690 and think that the few 14th- and 16th-century examples, meaning “accomplishment”, were probably formed on the Old French verb complir (“to accomplish”).[7]
It is a doublet of compliment.[1] Littré compares Old Occitan complement.[8]
Earliest recorded meaning
Its first record, in 1308, is in Aimé du Mont-Cassin's Ystoire de li Normant, in the phrase venir a complement, with the active sense “carrying out, accomplishment”.[2][3]
Semantic evolution
The abstract sense “accomplishment”, sometimes with a shade of “perfection”, gave way to the concrete sense “what completes something”, first found in a royal ordinance of 1347 about a sufficient supply of small coin.[2][3][8] This sense was then specialised in geometry (1690), astronomy and music (1732).[3][2]
In grammar the term was brought in by Du Marsais, between 1720 and 1750, to free French grammar from the Latin model, which spoke of the régime; the TLFi finds it in Abbé Girard's grammar of 1747.[3][2] The theological phrase complément de béatitude (1732), the extra bliss of the blessed after the Last Judgement, revives the old sense of fulfilment.[3][8] Until the First World War officier de complément meant a reserve officer.[9]
